A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

This report is on Some Perspectives on the Nato-WarSaw Pact Balance. Evaluation of the 'balance' between the Warsaw pact and nato involves a complex mixture of objective and subjective factors.

Pressing materials problems that must be solved before tritium can be used to produce energy economically in fusion reactors are discussed. The following topics are discussed: (1) breeding tritium, (2) recovering bred tritium, (3) containing tritium, (4) fuel recycling, and (5) laser-fusion fueling. (MOW)

The design of business data processing applications utilizing minicomputers requires special considerations throughout the development of the systems project. Minicomputer features, capabilities, and limitations must be closely examined prior to the implementation of the design phase. The design requirements of an inventory control minicomputer system currently being installed by the Data Processing Services Department of Lawrence Livermore Laboratory are presented.

Laboratory apparatus has been designed, built, and put into operation to study the supercooling of Sn--Si melts and the uptake of silicon from silanes. Values of supercooling of Sn--Si melts as high as 78/sup 0/C at 1100/sup 0/C and 39/sup 0/C at 1200/sup 0/C have been observed. Results to date have been limited by nucleation caused by foreign material floating on the surface of the melt. Spontaneously nucleated planar platelet growth has been observed at the Sn--Si supercooled surface having growth rates of approximately 0.5 cm/min. Homogeneous nucleation of silane decomposition has been studied at 1015/sup 0/C and 1135/sup 0/C. The flow rates of HCl required to suppress gas phase decomposition have been determined for silane flow rates up to 4.5 x 10/sup -3/ mole/min. Initial silicon uptake experiments have shown that at least 20 percent of the incoming silicon contained in a flowing silane gas stream can be incorporated into liquid tin at 1040/sup 0/C.

Scientists are finding increased applications for microprocessors as process controllers in their experiments. However, while microprocessors are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microprocessor programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result -- the LLL BASIC interpreter. 1 figure, 4 tables.

The purpose of this study was to obtain a simulation of the most rapid start-up thermal transient which would be encountered in the BIPS operation. As an aid in reducing the severity of the transient, it was agreed with the NASA that the case to examine would be determined by the following logic: (a) determine the lowest temperature at which a start could be accomplished using a 2 HSA configuration; and (b) define the transients for a 3 HSA start which was initiated when the heat source achieved the start temperature determined for the 2 HSA configuration of (a). This approach limits the transient analysis of the recuperator and the HSA to a single case. (The 2 HSA start requires a higher initial temperature due to lower thermal capacity with only two HSA's). The transient defined is ''worst case'' for either two or three HSA operation. In order to obtain the above data, several computer cases were run. A summary of the computer runs made is presented in tabular form.

The temperature distribution along a coaxial electrical cable can be determined by means of frequency-domain reflectometry if the cable has an inner sheath of a suitable temperature-sensitive dielectric material. Such a technique would have advantages in cost and convenience over the conventional method of placing a separate thermocouple at each point where the temperature is to be measured. It would be especially useful for underground applications in assessing geothermal reservoirs and in instrumenting in situ coal-gasification and oil-shale-retorting experiments.

The gamma-ray energy region from 120 to 350 keV was investigated using a 1-cc planar Ge(Li) detector. Plutonium isotopic ratios are presented for 0.25 g NBS Standard Reference Material. The results show the feasibility of obtaining /sup 240/Pu and /sup 241/Am isotopic ratios to better than 5 percent of the chemical value by using gamma-ray spectrometers having 600-eV resolution at 122 keV. A single exponential equation has been used to predict the equilibrium of a 1-in. x 3-in. calorimeter (Mound Laboratory Model 100). The formulas necessary for this prediction are presented with some preliminary results. This technique has proved to be successful in significantly reducing the time required to calorimetrically analyze a sample. The installation of the X,Y,Z transporter on a test frame and the computer programs necessary to test it were completed. Tests were performed to determine the sensitivity, thermal resistance, heat distribution error, and reproducibility of the APAS calorimeter. Two computer programs were written to facilitate the handling of inventory verification data. Seventy-nine samples were analyzed using calorimetric assay techniques. The results of the isotopic ratio determinations are presented. The overall uncertainty in the plutonium measurements is less than 1 percent. Gamma-ray spectroscopic techniques were used to measure …
